If you need to install the drivers under the Microsoft Windows XP operating system, please refer to the following document: Installation_Guide_for_WindowsXP.pdf.

  • Page 20: Programming Interface

    5.1 Configuring the encoder using the software tool ENC58 programmable incremental encoder is supplied with a software expressly developed and released by Datalogic Automation in order to easily programme and configure the device. It allows the operator to set the working parameters of the device and monitor whether the device is running properly.

  • Page 21: Starting The Program

    ENC58 PROG 5.2 Starting the program launch program just double-click ENC58_Rx_x_Datalogic_ENGLISH.exe executable file. Inside same folder find ENC58_Rx_x_Datalogic_ITALIANO.exe executable file to use the interface program with messages in Italian language, if needed. Press the OK button in the LICENSE page to go on. In this way you also agree with the terms and conditions of use of the software.
  • Page 22 ENC58 PROG The main page of the configuration interface will appear. It consists of a single page where all parameters and the complete diagnostic information concerning the connected encoder are available. Three sections can be found in the page: 1. a top left section where the parameters to program the encoder can be found;...

  • Page 23: Connection With The Encoder

    ENC58 PROG 5.3 Connection with the encoder If the PC and the encoder have been connected properly using the KIT ENC58 connection cable, as soon as you press the DISCONNECTED button the parameters in the interface are initialized to the values which are stored on the encoder memory. A proper connection is shown by the button turning green and changing its label into CONNECTED.
  • Page 24 ENC58 PROG If the encoder is not connected properly and the software tool is not able to establish a USB connection, then the USB to I2C not found: check connections!!! warning message appears on the screen. In such occurrence please check that the USB cable is connected properly to the USB port and the USB port is working correctly.

  • Page 25: Setting The Parameters

    ENC58 PROG 5.4 Setting the parameters WARNING Please always be aware that the parameters set in the interface are not permanent, they are only stored temporarily in the RAM of the encoder. For instance, should you disconnect the USB cable and so cut off the power supply, data which has been set previously would be lost! To save the data on the EEPROM permanently, after having entered...
  • Page 26 ENC58 PROG NOTE Please note that the maximum counting frequency of an encoder, expressed in kHz, results from the number of revolutions per minute (RPM) -i.e. its rotational speed- and the number of pulses per revolution (PPR) -i.e. its resolution. It can be calculated by using the following algorithm: RPM * PPR Maximum counting frequency (kHz) =...
  • Page 27 ENC58 PROG Example 1 Let's assume that the encoder is mounted on the driven draw roller of a slitter and the circumference of the roller is 753 mm. We can set a resolution of 7530 PPR (Resolution = 7530) to control the movement of the roller with a tenth of a millimetre resolution.
  • Page 28 ENC58 PROG We can set a resolution of 55000 PPR (Resolution = 55000) to control the movement of the cable and thus of the axis with a tenth of a millimetre resolution. In this way we convert a rotary measurement value (55000 PPR) into a linear measurement value, therefore we are able to control the 5.5- m long linear travel with a tenth of a millimetre resolution.
  • Page 29 ENC58 PROG at which the 0 pulse is located in the 360° revolution of the encoder shaft is displayed. Default = 0 (min. value = 0; max. value = 262143) WARNING Please check the position of the 0 pulse and set it if necessary whenever you set a new resolution next to the parameter Resolution...
  • Page 30 ENC58 PROG Z pulse width This parameter allows to set the width of the Index pulse (0 pulse) expressed in electrical degrees. Two options are available and selectable in the drop-down box: 90° and 180°. Please note that the 0 pulse having a width of 90 electrical degrees is synchronised with A and B pulses, while the 0 pulse having a width of 180 electrical degrees is synchronised with A pulse.
  • Page 31 ENC58 PROG Direction By default the phase relationship between A and B channels is so that the rising edge of A channel leads the rising edge of B channel when the encoder is rotating in a clockwise direction (see the Figure above in the page).

    ENC58 PROG For any information on the electrical connection of the Counting direction input refer to the sections “4- Electrical connection“ on page 7 and “4.9 Counting direction input“ on page 10. WARNING After having set the new counting direction it is necessary to set also the Index pulse.
